Figure 4

A basal action potential pattern of BrS identified in BrS1. (A and B) Representative AP waveforms recorded from a CON1 and a BrS1 paced at 1.0 Hz. The solid and dashed arrows indicate APA measured at phase-0 and phase-2, respectively. (C) The main AP parameters of CON1 and BrS1 are plotted and compared in bar-graphs. Values given are mean ± SEM. ||p < 0.00001; vs. CON1 (by unpaired t-test).
